customspeed officially supports fabric, forge, neoforge for Minecraft 1.21.10, 1.21.7, 1.21.5. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with customspeed – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if customspeed consumes the most tick time.
